What are examples of functions in real life?

Hint: First recall the definition of function then state some real-life examples of function.

Complete step by step solution: A function is a relation between two variables, where we can get the output for every input value.
Some real-life examples of a function are,
1.We can consider the ATM machine as a function, as for every input value we get an output.
2.A stamp is a constant function, as every time the output is the same.

The examples are ATM machines and a stamp.

Note: Sometimes students give the mathematical example as real-life examples, as they are unable to understand the meaning of a function, so first understand the meaning of a function then you can see a lot of things around you which you can express as a function.
